摘要： According to one embodiment, a memory control device includes: queues in channels; first controller; generator; and second controller. The queues hold write commands for data pieces. The first controller causes: (i) when a read command is received, and until the write commands are held in the queues, the channels are synchronized with each other, and processes of the write commands become ready to be performed, a read process based on the read command prior to the write commands; and, (ii) when the processes of write commands become ready to be performed, synchronization of the channels and write processes for the data pieces based on the write commands. The generator generates error correction codes based on the data pieces when the channels are synchronized with each other and the processes based on the write commands are performed. The second controller writes the error correction codes on the storage medium.
